WINDOW-SCREEN.

Specification of Letters Patent.

Patented Nov. i i, 1916.

Application filed September 22, 1915. Serial No. 52,023.

To all whom it may concern Be it known that I, FRANK L. HAwLnY, a citizen of the United States, residing at Blanchard, in the county of Skagit, State of Washington, have invented certain new and useful Improvements in lVindow- Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to window screens.

The object of the invention is to provide a screen or screens for windows made of material sufficiently flexible to be wound on a roller concealed at the bottom or top of a window frame and having one end secured to a window sash to be unrolled when the window is opened and thus occupy the space left by the sash and rerolled when the window is closed through the medium of mechanism operated by the closing movement of the sash with which the screen is associated.

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which Figure 1 is a front elevation of a window with the parts broken away to show theinterior construction; Fig. 2, a section on the line 2-2 of Fig. 1; Fig.- 3, a section on the line 33 of Fig. 1, and Fig.4, a section on the line ir- 1 of Fig. 1.

Referring to the drawings 10 indicates a window frame in which are slidably mounted upper and lower sashes 11 and 12. As the screen construction associatedwith each of the sashes is identical only that associated with the lower sash will be illustrated and described. Journaled within the sill of the frame 10 is a roller 13 upon which is adapted to be wound and unwound a screen 1 1. One endof this screen is secured to the lower end of the sash 12 in any suitable manner and said screen is adapted during the raislng and lowering of the sash 12 to move through a slot 15 in the sill of the frame 10. Secured to each end of the roller 13 is a pulley 16 for a purpose that will presently appear. Secured to the sash 12 at each side thereof is one end of a sash cord 17 which is trained over a pulley 18 mounted in the related side of the frame 10. Each sash cord 17 is then carried downwardly within the frame 10 and trained over the related pulley 16 and then carried upwardly and trained over a pulley 19 carried by a suitable bracket 20 mounted on the side of the window frame 10. The usual sash weight 21 isv secured to the remaining end of each sash cord 17.

From the foregoing construction it will be obvious that when the sash 12 is raised the screen 14. will be unrolled so as to occupy the space left by the sash. As the sash is lowered the cords 17 will rotate the roller 18 and wind up the screen 14, the weights 21 serving during the lowering of the sash to impart the desired rotation to the roller 13.

What is claimed is In combination with a window frame, a sliding sash therein a roller journaled in the sill of the frame, a flexible screen wound upon said roller and connected to the sash and movable through a slot in the sill, a sash cord connected to the sash, a pulley mounted in the frame and over Which said cord passes to the'interior of the frame, a

pulley on said roller over which said cord passes, a bracket on the frame, a pulley on said bracket over which the cord passes, and

a weight secured to said cord.

In testimony whereof, IaifiX my signature,

in the presence of two witnesses.
